Police said they were called to a home in the 4100 block of Chatham Road around 8:50 p.m. Thursday, where they found a 73-year-old man and a 31-year-old woman with multiple stab wounds.

Police said the 73-year-old man, Jerome Marlowe Sr., died at a hospital. The 31-year-old woman was in critical condition Friday morning, according to authorities.

Detectives said Jerome Marlowe Jr., 43, admitted to stabbing the victims, identified as his father and sister, in self-defense during an argument inside the home.

According to charging documents, Marlowe told police that he got into an argument with his sister about being too noisy and leaving lights on in the house. He said his sister threw a vase at him, so he went to the kitchen, got a knife and headed back to her room.

He said on his way, his father, Jerome Marlowe Sr., stepped in front of him and threatened to kill him if he didn't stop fighting with his sister, so Marlowe Jr. stabbed him several times in the midsection. Marlowe Jr. said he then stabbed his sister, who managed to run to a neighbor's house for help.

Witnesses said they saw Marlowe Jr. run after his sister before going back into his own home, according to the charging documents.

Police arriving at the scene said they found Marlowe Sr. on the living room steps, while the sister, who hasn't been identified yet, was on the front porch of a neighbor's home.

Marlowe Jr. was taken into custody at his home.

Charging documents showed that Marlowe Jr. had a cut on his thumb, which he admitted was from the stabbing, and he also had blood on his clothing. Police said they found the knife in the kitchen sink, where Marlowe Jr. told them he put it, as well as large amounts of blood throughout the house.
